Suitable Seeing laeh members 19 are' ex'- lended ironsjh openings formed :it the forks in the guides 9 and are adapted to engagethe lower Slat-pf each door section and lock the latter in raised position. It lwill be understood that by laterally pressing against the projecting end of the latch members S19-the same will be moved out of the Apath-of the door sections and the latter allowed to lower.

Suitable hasp members 20 are pivoted adjacent the ends of one of the slats of each at their upper ends to form upper and lower guide members, an upper and lower flexible door section adapted to move in said guides :to form a closure, a metallic lining on the `upper door section having a hinged portion to extend over the inner faces of the channels when 1n lowered position and to move ;out of engagement with said inner faces when in elevated position whereby the tension of said lining will direct the upper sectioninto said upper channel, and a similar lining on the lower doorl section having a fixed edge engaging the inner face oi' the channels whereby the lower door section will be guided into the lower guide members when in elevated position.

2. In a door structure, a palr of channel- `section of the door, the tension of which is guides termiiiiting at their upperv adapted to direct said sections into the uppermost guide member, andal similar lining on the other' door member adapted 'to guide said latter door section into the lowermost guide member when said sections are in elevated position.

3. A door structure comprising a pair, of channel-shaped guides, said guides being bifurcated at their upper ends to 'form upper and lower guide members, a door comprising an upper and lower section, a metallic lining on the inner face of said upper door section adapted to direct tension thereagainst and guide the same into the upper guide members, wings hngedly secured to the edges of said lining adapted to extend over the inner faces of the guide members when in lowered position, `a similar lining on the lower door section having fixed edges projecting over the inner faces of the guides adapted to move the lower door section into the lowermost guide members, and means to normally retain the door sections in their respective elevated positions.
